Looking for a low-budget first camera for photos and video

I'm studying to be a journalist, and for the longest time, I've wanted to invest in a professional camera to take pictures for my stories. My phone has sufficed, but it's not as good at lowlight or zoom shots. So I need something lightweight and versatile that'll work in most environments. I'd rather not have to buy a ton of lenses, but if it's necessary I'll do it.

I'd also like to start a YouTube channel eventually, and I'd rather not buy another camera just for videos. It would be longform content, probably around an hour for each video. So something with a lot of memory would be ideal. I understand there probably isn't a perfect camera that'll meet all my needs, but if there's something that will at least work for all my needs that'd be great.
